使对称

It is true that he used the old patterns all his life with dogged conservatism (another Sansculotte characteristic, by the way); but the imposed on them such an overwhelming charge of human energy and passion, including that highest passion which accompanies thought, and reduces the passion of the physical appetites to mere animalism, that he not only played Old Harry with their symmetry but often made it impossible to notice that there was any pattern at all beneath the storm of emotion.

不错，他一生非常保守地（顺便说一句，这也是激进共和主义者的特点）使用着旧的乐式；但是他加给它们以惊人的活力和激情，包括产生于思想高度的那种最高的激情，使得产生于感觉的激情显得仅仅是感官上的享受，于是他不仅打乱了旧乐式的对称，而且常常使人听不出在感情的风暴之下竟还有什么样式存在着了。
